A set of genes that are turned on only within time-limited windows—including genes encoding RNA binding molecules, let-7 microRNAs and IMP1—control developmental switches in stem cell properties between fetal development and adulthood.
A peptide derived from BK and JC polyomavirus protein VP2/3 inhibits viral infection by targeting a binding site in the pore of polyomavirus VP1 pentamers, enabling future VP1-targeted therapeutic strategies.
Super-resolution microscopy reveals, at nanometric-scale, the highly organized protein structure of viroplasms, the viral factories used by rotavirus to replicate its genome and assemble new viral particles.
Intersectin counterparts in yeast recruit WASP and WIP to endocytic sites to establish a robust multivalent SH3 domain-PRM interaction network which gives actin assembly onset a switch-like behavior in vivo.
Targeted SOCS3 null mice reveal that maturation of cortical bone comprises both pore closure and accumulation of high density bone, requiring local suppression of gp130-STAT3 in osteocytes and subsequent osteoclastogenesis.
The reduced ability of Drosophila imaginal discs to regenerate as they mature can be explained by the silencing of damage-responsive enhancers that regulate expression of genes required for regeneration.
